A new ``auto`` value for the configuration option
``upgrade_levels.compute`` is accepted, that allows automatic determination
of the compute service version to use for RPC communication. By default, we
still use the newest version if not set in the config, a specific version
if asked, and only do this automatic behavior if 'auto' is
configured. When 'auto' is used, sending a SIGHUP to the service
will cause the value to be re-calculated. Thus, after an upgrade
is complete, sending SIGHUP to all services will cause them to
start sending messages compliant with the newer RPC version.
